For example, we can compute artificial space-time diagram SUM, consisting of three different events A-C (Example: H. Meszarosova and P. Gomory, A&A 643, A140 (2020), Apendix A, part (a).):

• Event A: strong continuum emission with an intensity of 500 a.u. (arbitrary units) and a period of 900 s.
• Event B: a group of pulsations with a period of 60 s, the emission intensity of 10 a.u., and observed time interval of 100 - 500 s at coordinates Y = 20 - 8000.
• Event C: a small group of weak pulsations with a period of 9 s, an emission intensity of 1 a.u., and an observed time interval of 180 - 330 s at coordinates Y = 30 - 7000.

The WASEM divide the diagram SUM into three new separated ones. We can compare these separated results with the original events (A-C). Then we can select the individual row in separated space-time diagrams to compute their characteristic wavelet power spectra. They show their characteristic periodicity that can be compared with the periodicity in the original events.
